What is a Business Object?

A representation of a type of uniquely identifiable business entities, described by…

 a structural model

 an internal process model

 one or more service interfaces

Business processes operate on business objects.

(6)

What is a Framework?

„A software framework is an abstraction in which common code providing generic functionality can be selectively overridden or specialized by user code providing

specific functionality. …

Frameworks are similar to software libraries in that they are reusable abstractions of code wrapped in a well-defined API. Unlike libraries, however, the overall program's flow of control is not dictated by the caller, but by the framework. This inversion of

control is the distinguishing feature of software frameworks.“

What is BOPF?

BOPF - Business Object Processing Framework

 Pursues a modular step-by-step approach to implement and run business

objects that comply with the Enterprise Service Oriented Architecture

(8)

Advantages of Using BOPF (1)

Rapid Prototyping

 Quick setup of a running prototype of your business object with its most basic

services already enabled, such as create, retrieve, updated, delete, save, and query.

Reuse of Implementation

 Clear structuring of the business logic in small reusable parts using standardized

interfaces and a clear separation of concerns.

Highly Customizable

 Support enhancement and configuration options at every level, such as defining

the specific business logic and performance optimization attributes that are unique to your business object.

Less Implementation Efforts

 BOPF controls the application business logic as well as the data retrieval of the

(9)

Advantages of Using BOPF (2)

User Interface Modeling (Floorplan Manager Integration)

 Create user interfaces including personal object worklists for your business

objects without any coding

Status and Action Management

 Model a status diagram of your business object including special transitions and

actions

Change Documents Integration

 Record transactional changes of the data of business objects and check the

change history

Data Archiving

(10)

Advantages of using BOPF (3)

Modeled Field Control (Field Control Framework)

 Model the behavior of controls (e.g. enabled, disabled, read-only, mandatory)

related to the state of the business object

Integrated Transaction Management

Rule Management Engine Integration (BRF+)

 Use the rule management expression in order to define your logic

Output Management Framework Application Log

 Store your application log in a special application log business object

(11)

Who uses BOPF?

BOPF in SAP Business ByDesign is used for more than 66% of all business objects

BOPF in Business Suite is used by the following groups:

 SAP Quality Issue Management

 SAP Management of Change

 SAP Supplier Relationship Management

 SAP Transportation Management

Architecture Layers

User Interface (Floorplan Manager)

Consumer

Business Object Layer (BOPF)

Transaction Layer (BOPF)

(14)

Development Paradigms

Access to Business Object (CORE Services) only via a Defined API Clear Separation Between Changing and Checking Business Logic

 No mixture of methods that change the business object with methods that have

the purpose to check the business object’s consistency

Clear Separation Between Business Logic and Data Buffer

 Business logic is built on top of the business object and the buffer to be

independent of how and where data is buffered

 Business logic shall not be implemented within the buffer

Clear Separation Between Data Buffer and Database

 Easy exchange of the buffer algorithm (e.g. to gain performance)

BOPF Meta Model (1)

Meta Model

Business Object Model

Business Object Instances

 Contains Determination, Validation, Action

and other model elements, which are necessary to model a business object

 Uses the components of the meta model in

order to describe structure and behavior of a business object

 E.g. Customer_Invoice

 Instances of a business object model, created

at runtime

 E.g. “Customer Invoice” No. 231,

(18)

BOPF Meta Model (2)

Node

A business object is a hierarchical tree of nodes. A single node consists of a set of semantically related

business object data and the corresponding business logic.

BusinessObject Node Action Determination Validation Elements Association

The meta model defines elements that can be used to describe a certain business object. The most important ones are:

Elements

Elements represent business information (e.g. InvoiceID, InvoicePaid).

(19)

BOPF Meta Model (3)

Action Entities

 Changes the business object instance

 Is triggered explicitly by the service consumer

Determination Entities

 Changes the business object instance (side effects)

 Is triggered internally due to changes of the business object instance

Validation Entities

 Does not make any changes on the business object instance

 Consistency validations

 Action validations

Query Entities

 Search for business object instances that fulfill certain search criteria

Association Entities

(20)

Development Tools

SAP Internal Design Time (aka CONF_UI) BO Builder (aka Enhancement Workbench) BO Builder Test Environment (aka Test UI)

(21)

SAP Internal Development Environment

 Can be used internally in order to create, update, or delete business objects

 Allows to add entities (e.g. actions, determination, and validations) and attributes

(22)

Business Object Builder (BOB)

Create new business objects or enhance existing business objects by adding new nodes, new actions, new determinations, or new validations.

Enhance existing actions by adding a pre-action or a post-action that are automatically executed before (or after) the action of the base business object is executed.

(23)

Business Object Builder Test Environment (BOBT)

Test every business object using a generic graphical user interface. Execute entities and save or clean up transactions.
